pinyin我想用LuaLaTeX文档。- 我收到错误，如下所示。
- 根据 babel 手册（版本 3.32，最新），该
pinyin选项应该可以起作用。 - 我更新了我的 MiKTeX 安装，以确保我不会犯新手错误。
- Google 搜索结果如下https://packages.debian.org/jessie/amd64/latex-cjk-chinese/filelist其中包括
/usr/share/texmf/tex/generic/babel/pinyin.ldf。 - 我也没有在 babel 存储库中找到任何东西：https://github.com/latex3/babel。
! Package babel Error: Unknown option `pinyin'. Either you misspelled it (babel) or the language definition file pinyin.ldf was not found
问题：pinyin.ldf当我安装完整的 MiKTeX 时我应该从哪里获得它以及它是否应该自动安装？
\documentclass{article}
\usepackage[pinyin]{babel}
\begin{document}
Pīnyīn.
\end{document}

在用户@egreg 的帮助下，我找到了 ldf 文件，其内容如下pinyin.ldf：
% This is the file pinyin.ldf of the CJK package
% for hyphenating Chinese pinyin syllables.
%
% We use the latin-1 character code for `umlaut u' (0xfc). Additionally,
% the quote character "'" is used in its standard sense (resolving syllabic
% ambiguities).
